The Method

Everything on your device, nothing in the cloud

Almanox runs a full astronomy engine locally. No account, no sign-up, and it works with the signal off - the sky is the same whether or not you have bars.

1

Pick your spot

Use your current location or save the places you shoot from. Almanox computes the sun, moon, and sky for exactly where you stand.

2

Read the verdict

One score answers the only question that matters - is tonight worth it? See the best dark-sky window, the Milky Way core, and how much the moon gets in the way.

3

Plan the shot

Find the exact days the sun or full moon lines up with your direction, catch the golden hour, and get an alert before the sky is ready.

The Glossary

A field guide to the sky

The words the whole app is built around - and why each one is a reason to keep Almanox in your pocket.

The AlmanacAlmanac
A day-by-day table of the sky - when the sun and moon rise and set, the moon's phase, and how many hours of real darkness you get. Almanox is a living almanac for exactly where you stand, recomputed for your spot, not a generic printed one.
Best lightGolden hour
The stretch just after sunrise and before sunset when the sun is low and the light turns warm and soft. It is the light most landscape and portrait photographers wait for - and Almanox gives you the exact start and end for today, wherever you are.
Blue lightBlue hour
The short window before sunrise and after sunset when the sun sits below the horizon and the whole sky glows a deep, even blue. Prime time for cityscapes and moody skies - it comes and goes fast, so timing it to the minute matters.
Into the darkTwilight ladder
Darkness arrives in three steps - civil, nautical, then astronomical twilight. When astronomical twilight ends, the sky is finally black and the faint stars appear. That is the moment stargazers and astrophotographers actually start shooting.
The galaxyMilky Way core
The bright galactic center - the glowing, detailed part everyone photographs. It is only above the horizon for part of the year and part of the night. Almanox tells you when the core rises, peaks, and sets, and grades how good it will look.
The windowDark-sky window
The stretch of night with no sun and no moon washing out the sky. It is the only time deep-sky and Milky Way shots really work, and it shifts every night - which is exactly the thing that is tedious to work out by hand.
MoonlightPhase & illumination
How much of the moon is lit, from new to full. A bright moon floods the sky and drowns the Milky Way; a new moon leaves it pitch dark. Knowing tonight's moon is half the battle for any night shoot.
The answerTonight verdict
Almanox fuses Milky Way height, hours of darkness, and moon interference into one honest 0-100 score. Instead of cross-checking five things, you glance at one number and know whether tonight is worth heading out.
The alignmentSun & moon lineup
The exact days the sun or full moon rises or sets lined up with a landmark or compass direction - the planning behind those hero shots of a full moon behind a bridge or peak. Almanox searches the days ahead for you.
OverheadISS pass
When the International Space Station flies over bright enough to see with the naked eye - a steady, fast-moving point of light. Almanox gives you the next visible pass, its direction, and how high it climbs.
The figuresConstellations
The 88 named star patterns - Orion, the Big Dipper, Sagittarius over the Milky Way. Almanox draws all of them and the bright stars over your actual sky, in a star chart and through the AR finder, so you can point and name what you are looking at.

How is the Tonight score calculated?+
